According to my textbook it says rarefaction, is the less dense region of a longitudinal wave
The term for an area of high density in a longitudinal wave is a compression. This is where the particles are close together and there is an increase in pressure.
Rarefaction. It refers to the region where the particles are spread apart, leading to a decrease in density in a longitudinal wave.
wavelength
The term that describes the distance between any two crests in a transverse wave or the distance between any two rarefactions in a longitudinal wave is called the wavelength.
That is the wavelength.

Your question is hard to answer for you have not made it clear what you are asking. The term "is less dense than?" is not a question. If you were to ask "What is less dense than snow or water?" That would be a correct question.
The Lithosphere is the ridged layer of Earth that is about 100 km think and generally less dense than the material below it. This layer is the tectonic plates the move along on the anthesphere.
The axis is the medical term meaning the longitudinal or long portion of a structure. The Axis of the uterus points up and down (cephalocaudally).
If you meant optical density by the term 'denser ' Then the answer is.... The light bends towards normal when it travels from a optically less dense medium to optically dense medium. So angle of incidence is greater than the angle of refraction
Osteoporosis is a bone disease in which the bones become less dense and more brittle. Osteosclerosis is the medical term meaning abnormal hardening of bone.
Feces (the technical term) are less dense than water. If an object is less dense than water, it floats. If it is more dense than water, it sinks.
The term for an area of high density in a longitudinal wave is a compression. This is where the particles are close together and there is an increase in pressure.
Rarefaction. It refers to the region where the particles are spread apart, leading to a decrease in density in a longitudinal wave.
The term "petrous" usually refers to the dense, hard part of the temporal bone in the skull, specifically the petrous part. This part of the temporal bone protects delicate structures like the inner ear and houses important nerves associated with hearing and balance.
The term that best describes the rocky outer layer of the Earth is the "crust." The Earth's crust is divided into two types: the oceanic crust, which is thinner and denser, and the continental crust, which is thicker and less dense.
